The couple's wedding invitations were designed by Lehr & Black, who also created invites for Kim's sister Khloe and her husband Lamar Odom, Gwen Stefani and Gavin Rossdale, and Fergie and Josh Duhamel, among others.

The invite, which arrived at guests' homes housed inside its own box, is embellished with hundreds of jet black hematite crystals.

The couple got engaged in a most elaborate fashion on May 18, complete with a 20.5-carat engagement ring.

"It was everything I ever dreamt of and more," Kardashian has said. "I think when you know ... you know."
